Kamtech Solar has installed hundreds of systems, and most of them work quietly for years. But we found a pattern of unresolved post-installation failures that should give you pause. In one case, a homeowner spent two months chasing the company to fix roof leaks that started the day panels went up, ultimately paying $5,000 out of pocket for repairs after Kamtech stopped returning calls. Another reviewer reported half their system going dark after a critter guard install, with one dead panel still offline months later. We counted 17 reviews describing vanishing customer service after payment cleared, permit paperwork never filed, or systems that never received the required city inspections. On the positive side, 82 reviewers praised the installation workmanship itself, and longtime customers report stable performance once everything is running. But nearly every negative review mentions the same problem: when something breaks, you may wait weeks for a callback, if you get one at all. If you're willing to risk being stranded mid-repair, the upfront install quality is solid. If you need a company that picks up the phone after year two, keep looking.
If you're hoping for a set-it-and-forget-it solar experience, Kamtech's post-installation support record makes that unlikely. When systems fail or permits stall, multiple customers report waiting months for responses or paying out of pocket to fix issues the warranty should cover.
In July 2022 Elizabeth C had solar panels installed on her house and discovered the crew refused to repair the roof before mounting the array. Shortly after the installation she began getting roof leaks and reached out to the company; it took nearly two months before anyone showed up, only to tell her the problem wasn’t the roof. She paid to have the gutters and the chimney repaired, yet the leaks persisted. Repeated phone calls and emails went unanswered, so she hired a separate roofing contractor who found the roof “completely rotted and in bad condition” and charged her an additional $5,000 to fix it. With Kamtech Solar Solutions holding her payment and no follow-through on their earlier commitments, she describes the company as unprofessional and incompetent and regrets doing business with them. The clearest takeaway: she ended up covering a $5,000 roof repair out of pocket for damage the installer wouldn’t address and then ignored her attempts to resolve it.
A few years ago Alex had Kamtech fit an 18-panel system on his house with an unusually shaped roof — other companies had offered only 10–12 panels, but Kamtech managed to squeeze in enough to meet his needs. The array worked well for years until he asked them to install critter guards to keep squirrels from nesting under the panels. After the guards went on, roughly half the panels stopped producing. Kamtech returned twice and got most of the array back online, but one panel stayed dark because its microinverter had died. Two days ago Kamtech finally replaced that remaining faulty panel, and now every panel is operational — the lasting impression being that they were the only installer willing to handle his tricky roof and that they stuck with the job until the last microinverter was replaced.
Mari had rooftop solar installed in 2018 and, when a roof problem appeared in 2024 that requires the panels to be removed and reinstalled so they can determine whether the array caused the damage, she discovered she couldn’t get the paperwork she needs. Since May 2024 she has been pressing Kamtech Solar for three specific documents: the installation contract, the walk-through inspection reports from before and after the panels were installed, and any Department of Buildings and Con Edison inspection records. By September she still hadn’t received them. She kept calling—about once a week—and was repeatedly told a manager would call back, but no manager ever provided the files. Her husband handled the original project and trusted the work was done properly; the absence of any inspection proof has shaken that trust and raises the possibility that required inspections never happened. Mari says she is legally entitled to these documents and intends to keep demanding them; if the company doesn’t produce them she plans to seek legal representation. Takeaway for prospective buyers: secure copies of the contract and all inspection paperwork at the time of installation, because trying to

Jay Greenberg had solar panels installed on his roof by Kamtech many years ago. An engineer climbed up to measure the layout, and the company stayed involved throughout the process. They even located a lender who offered financing at a reasonable interest rate. Years later, when he discovered a roof leak unrelated to the installation, Kamtech hunted down the source and repaired it. He hasn’t had any problems with the panels since the install and walked away impressed by their follow-through.
John had a Kamtech solar system installed in 2019 on his home and hasn't experienced any problems since. When SunPower filed for bankruptcy recently, he leaned on Kamtech staff — especially Chris and Egor — who patiently walked him through the situation and answered his questions. What stuck with him most was that two named technicians took the time to explain the bankruptcy’s implications for his system, reinforcing that the company continues to provide hands-on support after installation.
Jason first had the company install a solar system in 2020, and when he needed to expand the setup recently he turned back to the same team. He found their service responsive, the communication clear, and the product reliable — enough that he chose to add onto the original system instead of looking elsewhere. The standout detail is the repeat business: trusting them years later to expand the array feels like a practical endorsement of their workmanship. For buyers who want a provider that will support both the initial install and later upgrades, his experience highlights consistent service and dependable equipment.
Neela Rose hired Kamtech Solar to install panels on her home a few years ago and discovered it has been a solid financial investment. She found the installation team consistently professional and efficient, and she leaned on a knowledgeable customer-service group for clear support after the work finished. The detail that stuck with her was how smoothly the entire process was handled — strong installation paired with dependable follow-up.
Greg chose Kamtech to put 36 solar panels across his house roof and garage. He ended up with a smooth installation—no hiccups—and a system that has run reliably. After 18 months he still finds everything working as expected and feels he made the right decision. What stuck with him most was the trouble-free install across two roof surfaces and steady performance through the first year and a half.
Clive hunted for a reliable SunPower system in 2018 and, after a friend’s recommendation, chose an authorized dealer—Kamtech Solar Solutions—following detailed conversations with a company rep and an in-house engineer about panel size and specifications. Kamtech’s crew completed the roof installation in a single day, tucking the electrical conduit into the basement ceiling, and impressed him with their speed and neatness. He then waited a few weeks for the DOB inspection and ConEd permission to energize; the system finally came online just after Christmas 2019. Once running it began to offset the household’s electricity immediately, and by spring—with longer days—it started banking kilowatt-hours to his ConEd account; his out-of-pocket bill dropped to about $20 a month. Over more than four years of operation he encountered no major problems, only a brief one- or two-day gap in performance data during a software upgrade that Kamtech monitored and ConEd confirmed the panels themselves kept producing. Kamtech handled the NYS rebates and filed for his NYC property tax credits, while he claimed the federal credit through TurboTax; the NYC tax credit lasted four years and recently l
Mark had Kamtech install a solar system on his home three years ago and remains extremely satisfied. The crew delivered a neat, professional installation, and the company has stayed responsive ever since, taking care of questions and follow‑ups without delay. The standout detail was Krystof’s hands‑on pride in the work — he stayed involved and showed genuine care for him. That steady responsiveness combined with a technician who treats the job personally is the specific takeaway a prospective buyer will remember.
Three years after the company installed solar panels on her home, Karen hired a gutter cleaner who discovered openings where several panels sat; inside, water stains and flaking on the ceilings made it clear the roof was leaking. She contacted the company two months ago and was promised a project-team callback within 24 hours — that callback never arrived. Since then she has called repeatedly and only reached voicemail. What makes this experience stand out is not just the damage but the after-sales silence: the company pursued the sale but became effectively unreachable when a repair was needed. The specific takeaway for prospective buyers is simple and concrete — get post-installation response commitments in writing and a direct service contact, because Karen’s promised 24-hour follow-up never materialized.
Long-term satisfaction for Kamtech Solar Solutions drops to 3.4 ★ compared to early reviews. This decline is worse than 75% of installers we looked at.
Long-term reviews carry the most weight in our methodology because they are most representative of what you should be paying for: a system that will perform for years.
